GH2 with Panny 100-300. I backed off a bit from full zoom for framing, then changed my mind in PP and cropped a bit, so I think this image is within the spirit of this thread.

What I like about this photo technically is how the boardwalk shows the limited depth of field when this lens is wide open, and how it has pretty good resolving power wide open even at (almost) full zoom as long as you keep the shutter speed high enough (1/1000 in this case) - zoom in on the skates and you can see quite a bit of detail.
